battery: stub out battery_is_present if disabled
There are a number of potential callers that care if there is a battery,
but for boards that don't support batteries (chromeboxes) we can let
them skip implementing this stub.
Tests default to battery present, but they can provide their own
per-test implementation if desired.
Some PD battery presence checks have been disabled when battery support
is disabled; these are irrelevant when there is no battery, and they
cause linking failures because they depend on both the charge manager
and battery presence.
